First, prevention and control of powdery mildew. For fruit trees with powdery mildew, excavate an annular groove 10-20 cm deep from the plant 15 cm away, and apply 10-20 kg of grass ash in the ditch and cover with a thin layer of soil.
Second, the prevention of rust fruit disease. For the existing apple tree, dig a 50 cm wide and 60 cm deep circular groove at a distance of about 50 cm from the root diameter, and then apply the grass ash as the base fertilizer into the ditch, pour enough water, and press the new soil. Just fine.
Third, prevention of root rot. The effect of grass ash on the control of root rot of pear, peach and hawthorn is very good. The method is to first open the soil of the root of the fruit tree, remove the soil around the root of the root, scrape off the root bark of the disease, and after drying for 24 hours, each plant covers 2.5 to 5 kilograms of fresh plant wood ash, and then covers the soil.
Fourth, the prevention and control of mites. Soaking 50 kg of water with 10 kg of grass ash for 48 hours, taking the filtrate to spray, can effectively control the mites on the fruit trees.
Fifth, prevention and control of blight, anthracnose. For the diseased seedlings, the grass ash is applied to the ridges, and the amount of 667 square meters is 30-50 kg.
Sixth, prevention and control of early defoliation of fruit trees. The leaching solution was prepared by soaking with 8 kg of grass ash for 100 hours in water for 100 hours, and the liquid was mixed with the sterilizing agent to have a certain prevention and treatment effect on the early defoliation of apple.
Note: When spraying the grass ash fertilizer on the foliar surface, use the clarified liquid after soaking to prevent the leaves from being contaminated. Grass ash is an alkaline substance and cannot be used in saline-alkaline soil. (Pan Jilan)
